【摘要】：目的评价负压封闭引流(VSD)技术在肢体皮肤慢性溃疡中的疗效及其对周围组织代谢的影响。方法选取2014年6月2016年6月对84例皮肤慢性溃疡患者的创面分别以VSD技术(实验组62例)及常规清创、换药方法(对照组22例)进行处理最后采用皮瓣移植修复,比较两种方法的疗效及周围组织经皮氧分压。结果实验组中平均手术清创次数为(1.9±0.4)次,平均住院日为(24±4)d,并发症发生率3.2%,皮瓣修复手术当天TcPO_2平均值(47.5±7.2)mmHg。对照组中平均手术清创次数为(3.1±0.9)次,平均住院日为(38±7)d,并发症发生率为40.9%,皮瓣修复手术当天TcPO_2平均值(35.3±6.8)mmHg。所有指标两组间差异有统计学意义(P0.05)。结论VSD技术联合皮瓣修复可改善慢性溃疡创面周围组织的氧分压,降低术后并发症发生率,且手术次数及住院日较常规换药处理明显减少。
[Abstract]:Objective to evaluate the effect of negative pressure sealing drainage (VSD) technique on the metabolism of peripheral tissues in patients with chronic ulcers of extremity skin. Methods Eighty-four patients with chronic skin ulcer were treated with VSD technique (experimental group, 62 cases) and routine debridement (control group, 22 cases) from June, 2014 to June, 2016. To compare the efficacy of the two methods and the pericutaneous partial pressure of oxygen. Results in the experimental group, the average number of debridement was (1.9 卤0.4), the average hospital stay was (24 卤4) days, the incidence of complications was 3.2, and the average TcPO_2 was (47.5 卤7.2) mmHg. on the day of flap repair. In the control group, the average number of debridement was (3.1 卤0.9), the average hospital stay was (38 卤7) days, and the incidence of complications was 40.9.The average of TcPO_2 on the day of flap repair was (35.3 卤6.8) mmHg.. The differences between the two groups were statistically significant (P0.05). Conclusion VSD combined with flap repair can improve the partial pressure of oxygen in the tissue around the wound of chronic ulcer and reduce the incidence of postoperative complications.
